1 Claim. (Cl. 30-219) This invention relates to a hair clipper.

The' object of the invention is to provide a hair clipper' which isprovided with a vacuum means or mechanism so that as the hair is cut' bythe cutting mechanism, the cut hairs will be sucked into a suitablereceiver or chamber within' the device.

Another object of the invention is to provide a hair clipper which canbe conveniently held in the hand, and wherein a motor means is providedin the hair clipper for simultaneously operating the cutting mechanismandv whrein the motor means also operates a suction cre ating fan sothat as the hair is cut by the cutting mechanism, the hair will besucked into a suitable compartment or chamber'within the clipper so asto insure that the hair can` be cut in a clean and sanitary andadvantageous manner.

A stillfurther object is to provide a simple and inexpensiveconstruction for performing the stated functions.

With these and other objects inview, this invention consists in certainnovel features of construction, combinations and arrangement of parts tobe hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had tothe following description and accompanying drawing, in which:

Figure 1 is a longitudinal sectional View illustrating the combinationhair clipper of the present invention.

Figure 2 is a sectional view taken on the line 2-2 of Figure 1. v

Figure 3 is a sectional view taken on the line 3--3 of Figure 2.

Figure 4 is a sectional View taken on the line 4-4 of Figure 2.

Figure 5 is a sectional view taken on the line 5-5 of Figure l.

Referring in detail to the drawings, the numeral indicates the hairclipper of the present invention which comprises a housing 11, Figure 1.A shaft 13 is driven by a motor 12, and the motor 12 is adapted to bearranged in an end of the housing 11. Mounted on the shaft 13 is a cam14, and the shaft 13 also serves to operate or rotate a fan 15 so as tocreate the necessary suction.

The housing 11 is provided with a chamber 16 which is adapted to receivethe cut hair, and a passageway 18 communicates with the chamber 16 sothat the cut hair can be sucked in from the vicinity of the cuttingmechanism 21, and this cut hair will them pass through the passageway 18and be received in the chamber 16. A valve 19 is provided forcontrolling the flow of air through the passageway 18, and the valve 19is controlled by means of an adjustable pin or screw member 20.

As shown in the drawings, the cutting mechanism 21 includes a stationarybody member 22 which has a bar 23 secured thereto or formed integraltherewith, and the bar 23 is received in a slot 24 of a support memberICS 29, the support member 29k being an integral part: ot the housing.11. A screw member` 25l extends through the support member 29 andengages the bar 23, as for example. as shown in Figure 1.

The cuttingv mechanism. 21 includes in addition. to thestationary bodyvmember 22', a movable cutter memberY 26, Figure 3, and the body member22 is provided withl teeth 27 which are adapted tov coact withk teeth28.on` the movable cutter member 26.

Connected tothe support member 29 is a pivot pin 30 which has a bearing31 rotatably mounted thereon, and an arm 32 extends rearwardly from thebearingl 31; and is secured thereto or formed integral therewith. Thearm 32 hasa. U-shaped bracket 33' on itsl rear end,- and as shown inFigure 5 for example, the spaced apart portions of the bracket 33 arearranged in engagement. with the cam 14. The arm 32Y includes portions34, 35, and 36- which are arranged angularly with respect to each other,and a4 suitable clearance. spiace, is provided. in the housing 11 forpermitting the arm. 32 to move4 back and forth as the motor 12.isactuated. A manu-- allyoperable switch 371 is provided for`controlling actu.- ation of the motor I12, and the motor 12 may beconnected to a suitable source of electrical energy by means` of thewires 38.

Extending from the bearing 31 and connected thereto is a finger 39,andthe finger 39 is providedv with aslot 40 therein, Figure 2. A link 41is adjustably connected to the finger 39, and the link 41 includes an4angularly arranged portion 42 which is connectedA to the movable` cuttermember 26 by means of a securing element 43. A- securing element orscrew member 4,4' extends through` the slot 40 and is connected to thelink 41, and a coil spring 45 is interposed between the securing element44 and the bearing 31, Figures 1 and 2.

The numeral 46 indicates a guard'or shield'which is connected to thecutting mechanism 21, and the guard 46 is held in place by means ofsecuring elements 47 which securing elements 47 extend through slots 49in the movable cutter member 26. The guard 46 is provided with a cutawayportion 48 that provides sufficient clearance for the end portion 42 ofthe link 41.

From the foregoing, it is apparent that there has been provided a hairclipper which is adapted to be used for conveniently cutting a personshair and creating a vacuurn so that the cut hair will be sucked into areceiver such as the receiving chamber 16. According to the presentinvention, the housing is provided with a cover 50 which can be removedas for example when the chamber 16 is to be emptied of the cut hair.

In use, by turning on the switch 37, electrical current will cause themotor 12 to be actuated so as to rotate the shaft 13. As the shaft 13rotates, it rotates the fan 15 so that a suction will be created wherebythe hair which is cut by the cutting mechanism 21 will be sucked inthrough the passageway 18, and this hair will then be received in theYchamber 16. The screen 17 will prevent the hair from accidentallyleaving thev chamber 16.

At the same time, as the shaft 13 rotates, it causes rotation of theeccentric or cam 14, and since the U- shaped bracket `33 on the end ofthe arm 32 is arranged in engagement with the cam 14, it will be seenthat the arm 32 will be swung back and forth on the pivot pin 30. Thismovement of the arm 32 will cause back and forth rotation of the bearing31 on the pin-30 which in turn will cause corresponding swingingmovement of the linger 39 and link 41. Since the link 41 is secured tothe movable cutter member 26 by means of the screw 43, it will be seenthat the cutter member 26 will be reciprocated or moved back and forthwith respect to the stationary part 22rof the cutting mechanism 21 sothat the teeth 28' and 27 will coact to sever or cut the hair.

By adjusting the screw in or out, the position of the control valve 19can be changed s0 as to regulate the amount of vacuum created in thepassageway 18.

The parts can be made of any suitable material and in different shapesor sizes.

The guard 46 may be made of any suitable material such as spring steel,and the necessary tension will be kept on the clipper head blades, andthe assembly will be properly held together. The chassis or housing canbe mates and using batteries which can be inserted in the receiver thatis used for the hair. It can also be converted or made into a portablecombination hair clipper by exchanging motors only and placing thebatteries in another container.

Thus, it will be seen that there has been provided an electricallypowered hair clipper which is adapted to cut hair and pull the hair fromthe blades at the same time and thus a person can have the hair cut in amore cool and cleaner fashion or manner.

As stated previously, the electric motor 12 rotates the cam 14 whichcauses movement of the clipper blades, and the fan 15 is on the sameshaft 13 that the cam 14 is on. The fan blades create a vacuum whichdraws the hair from the clipper blades into the receiver 16, and thereceiver can be emptied after each haircut, or when full.

The clipper head 21 may be easily attached or removed, and the spring 45keeps the clipper blades from chattering and keeps the necessary tensionon the blades. The screw member 25 helps maintain the clipper headassembly attached to the housing. If desired, a cloth or paper liner canbe used in the chamber or receiver 16. The fan blades may be of anysuitable type to create the desired vacuum. The motor 12 may be of thereversible type for blowing the hair out of the receiver as for examplewhen a liner is not used. The cover may be transparent to determine whenthe receiver is to be emptied.

Minor changes in shape, size and rearrangement of details coming withinthe iield of invention claimed may be resorted to in actual practice, ifdesired.
